So I upgraded to Lion and the Snow Leopard Server admin tools were deleted from my hard drive. Uh ho. When trying to install the old Snow Leopard Server Admin tools you get the following:
Oh noes! You can't install Snow Leopard Server Admin Tools on Lion!.
Before freaking out I checked out Apple's downloads page and found Lion Server Admin Tools posted. I downloaded and tried out and thankfully they work and I can fully admin my 10.6 Servers again.
I will be upgrading them to Lion soon, and I intend to post gratuitously about it but at least I still have time to consider my migration strategy.
